Etymology.

Amsa is a Quechuan word that means dark, opaque, or confused.

Diagnosis.

The species Gaujoptera amsa has similar morphological characters with species of Millerana , however, it is easy to identify because the thorax has no spots or patches, but is completely marbled with black, gray, brown, and sulfur-yellow scales. The forewing is dark sulfur-yellow with a blurry pattern in gray. Additionally, the genitalia have a simple valva without any lobe or protuberances, and a small clasper is present.

Description.

Head. Palp with last segment black with few yellow scales on tip; frons marbled. Thorax. Marbled in black, gray, brown, and sulfur-yellow. Wings. Forewing length: male 18-20 mm; forewing marbled with wing pattern in gray; pattern blurry; orbicular spot barely visible in yellow; a narrow lunate marking on reniform spot; terminal lines zigzag; hindwing hyaline with sulfur-yellow fringe. Leg. Prothoracic and mesothoracic legs sulfur-yellow with some brown spots; tarsi brown and yellow; metathoracic legs marbled in brown and yellow with tarsi sulfur-yellow. Abdomen. Sulfur-yellow with a black line of tufts in middle of abdomen on A1-A5. Male genitalia. Valva rectangular, simple; saccular region wide; apex densely covered by setae; clasper small, triangular; juxta shell-like; tegumen narrow; uncus small; aedeagus short, almost same width as vesica; vesica ovoid with a line of minute spines in middle, positioned diagonally.

Immature stages.

Unknown.

Distribution.

Remarks.

Most of the specimens are very damaged and could only be identified by genitalia examination, except the holotype and paratype (Figs 35 , 36 ).
